ALFRED O. GUTSCH AND ELLA C. GUTSCH, OF SI-IEBOYGAN, WISCONSIN.

GAS-BURNER ATTACHMENT.

Application filed January 7, 1916.

To all whom it may concern Be it known that we, ALFRED O. GUTscH and ELLA C. Gu'rson, both citizen of the United States, and residents of Sheboygan, in the county of Sheboygan and State of lVisccnsin, have invented certain new and useful. Improvements in GasBurner Attachments; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates to new and useful improvements in means for economically utilizing the heat from an open gas stove and is more particularly directed to such means of that type including a pair of hood members and a passage-way connecting the hood members whereby when one of the hood members is disposed about a burner,"

the heat may be utilized for receptacles disposed upon both hoods.

It is the object of the present invention to improve the efficiency of devices of this character particularly with respect to the procurement of a structure wherein a minimum amount of heated gas is permitted to escape.

It is further an object to provide a device of this nature which is readily attachable to conventional gas stoves in a manner compassing the aforementioned object.

With the above objects in view the invention consists in certain peculiarities of construction and combination of parts as set forth hereinafter with reference to the accompanying drawings and subsequently claimed.

In the drawings:

Figure 1 represents a sectional elevation of a portion of a gas stove, the burners of which are incased within a hood attachment embodying the features 'of our invention, the section being indicated by line 1-1 of Fig. 2, and

Fig. 2, a detailed plan view of the hood attachment with parts broken away and in section, as indicated by line 22 of Fig. 1.

Referring by characters to the drawings, A represents the burner pan of an ordinary stove and B the top grid under which is aflixed gas burners C, C. Fitted over the gas burner C is an open top circular hood 1, which, for clearness of description, will be referred to as a main hood. The bottom of the hood is open and rests upon the floor A of the pan, whereby a chamber is formed in connection therewith. The top Specification of Letters Patent.

of the hood is inwardly flanged at 1 to form a lid opening above the burner C, which lid opening as shown in this instance, is closed by a lid or cover 2 that rests upon the flange 1, thus forming a closed cham her in connection with thehood for incasing the burner. In order to adjust the hood to the burner and its supply neck 0, the side-wall of said hood is provided with a vertical slot 3 that extends to the bottom thereof, whereby the burner neck may be adjusted with relation to the hood and after such adjustment the slot is closed by a slide 4 which is arranged in dovetail union with the edges of said slot. A similar auxiliary hood 1." is also provided for the juxtaposed burner of the stove, whereby a pair of said burners is incased, one of which only is ignited in a cooking operation and, as shown P in Fig. 1, the burner C, which is located in the main hood, is put into use and the flame thereunder is preferably confined by the lid, but it is understood that in some instances the lid may be entirely dispensed with and the vessel, as indicated by dotted lines, may form a closure for the top of said hood to produce the same result. Thus the vessel is subjected to the direct heating influence of the ignited burner thereunder.

In order to direct the surplusage of heat from the main hood to the auxiliary hood, each of said hoods is provided with a cylindrical neck 5, which are in telescopic union, as shown in Fig. 1, to thus form a communicating passage between the hoods. Hence, as indicated by the arrows, the flow of the heat waves will be directed from the burner C to the chamber of the hood A, whereby a second article or cooking utensil, as indi cated by dotted lines, will be subjected to a cooking temperature. The bottom of the vessel, in this instance, will form the top closure for the auxiliary hood, whereby the heat units will have a more direct influence. In order to provide a secondary air supply to the burner which is ignited, the slide closed slots 3 in the hood members are preferably formed with hexagon end throats for engagement with the circular necks c and 0' of the burners, whereby air crevices will result to provide the necessary oxygen for perfeet combustion. In some instances, however, these vents may be dispensed with and air for combustion may be supplied through the open top hood of the set.

Thus it will be seen that a simple and Dual economical article is produced for fitting a standard type of stove and either burner may be utilized for accomplishing approximately the same result as two burners under the ordinary conditions. It is also manifest that in instances where the device is attached to a single burner stove, the auxiliary hood will be equally eflicient for cooking purposes as the second burner O incased has no function under ordinary conditions except to be used selectively or in instances where the naked fla me is desired for cooking the contents of separate containers, under which conditions the lid member 2 would be removed. It is also obvious that. where an intense heat is desired at a particular burner, both of the same may be ignited and cooking utensils placed thereover, whereby the auX- iliary heat from the combined burners is confined as, for example this may be desir able when large boilers are to be used and a single vessel may be seated over both hoods.

While we have shown the hoods cast each in. one piece and in telescopic union, it is obvious that they may be made of sheet tin or any other suitable material without departing from the spirit of our invention and attention is also called to the fact that the necks 5 which form the passage between the toward their ends to more effectually form unobstructed heat channels from one hood to the other. liVe claim:

The combination of a gas stove having a burner pan and burners positioned thereabove, open top and bottom hoods resting upon the bottom of the pan whereby the bottoms of the said hoods aieclosed, one at least of said hoods being disposed about and eX- tending above a burner whereby to incase the burner, said hood having an open slot in its side walladapted to receive the neck of the burner, a closure plate for the lower portion. o'l. the slot having grooves slidably receiving'the edges of the slot, a communicating passage between the hoods and means for closing the tops of the hoods.

In testimony that we claim the foregoing we have hereunto set our hands at Sheboygan in the county of Sheboygan and State of lVisconsin in the presence of two witnes'ses.
